. HORN-LOCK.

citizen of Hungary, and l, Josnrii NovoniL`` sinn, a citizen oftlieUnited States, and I, PETER DziGA, a Ycitizen of Austria, allresiding at Passaic, county of Passaic, and State of New Jersey, haveinvented certain new and useful Improvements in Horn-Locks, of which thefollowing is a speciiication.

This invention Vrelates to improvement-s in signal horns, such as areused in connection with automobiles and like vehicles to indicate theirapproach.

The principal object `of the invention is to provide a locking meanswhereby the horn may be prevented from operating at undesirable times. yj

This and other like objects are attained by the novel construction andcombination of parts hereinafter described and shownvin Y theaccompanying drawings, forming a (disclosure, and in which- Y Figure 1is a vert-ical sectional view taken through a conventional type ofautomobile horn and indicatingthe application ofthe invention.

Fig. 2 is a transverse or horizontal sectional vicw taken on line 2-2 ofFig. 1, and Fig. 3 is a fragmentary interior view,

similar to F ig. 1, but showing the parts in` another Position.

Referring to the drawings, ,the automobile horn is comprised of acylindrical casing 10, formed with a bottom 11, and having an outwtrdlyHanged edge element 12, turned upward at the top 13, in which is secureda diaphragm 14, by a plurality of bolts 15 which also hold in engagementtlielianged portion 16 of the horn mouth 17.

Rotatably mounted transversely in the casing 10 is a shaft 18 on whichis rigidly engaged a spur pinion 20 and spaced therefrom is a ratchet21, while rotatably mounted upon the shaft 18, between the pinion andratchet, is a` relatively large toothedl wheel 22 having secured at itsside a plurality of disks 23, the same acting as a fly wheel, and areactuated by a pawl 24 engaged in the teeth of ratchet 21, the pawl beingpivoted on the pin 25 to the outer disk.

Motion is transmitted to the pinion 20v by means of a rack 28, formedupon a rectangular bar 29, extending through projections 30, formed withthe casing, the rack bar Speccation of Letters Patent.

being provided with an actuating head or knob- 32, and guided internallyof the casing in the track-way 34, it being normally projected outwardlyby a coiled spring 34 (not shown) i The teeth of the wheel 22V areadapted to make contact with the point 36 of a screw radjustably securedin a hub 38 formed with the diaphragm 14, which is thus caused Vto emita loud and raucous sound at the pasusual type.

Y Pivoted on the pin 47, set in the plate eX` tension 42, is a lever 48,its front portion bedrawn normally toward the center of the casing dueto the pull of a coiled tension spring 56, engaged at its opposite endwith the pin 52. In its upper portion, is a seat 58 adapted to makecontact with the bolt 46 of the lock when the same is in an outwardposition, thereby raising the detent 50 from engagement with the rack,allowing it to slide in the ordinary manner.

The pendant lever is partially guided by a bent plate guard which alsoacts as a guide for a wire rod 62, formed with an eye 63, encircling apin 64, fixed in the side of the lever 55 and provided at its opposite,outer end with a plunger 66, extending through the casing 10 and havingan enlarged actuating head 67, by which it may be pressed into thecasing, thereby moving the lever 55 out of engagement with the bolt L16and permitting the detent 50 to engage with the rack teeth, preventingthe horn from being operated until a lrey has actuated the lock.

From the foregoing it will be seen that a effective device has beendisclosed, for preventing the unauthorized actuation of a horn or signalof the type described, so that if the vehicle be left unattended, thehorn can not be sounded until the lock has'been actuated.

Having thus described Your invention and set forth the manner of itsconstruction, apfplication and use, what we claim as new, and desire tosecure by Letters Patent, is-

l. In a horn lock, the combination with a horn adapted to be actuated bythe movement of a rack, and a lock fixed in the casing of said horn, oflevers pivoted in said casing adapted to be raised when the bolt of saidlock is extended, a detent carried by one of said levers, and means fornormally drawing said detent into engagement with Vsaid rack, whereby itis prevented from operation, a pendant lever pivoted on the v ment withthe teeth of said rack, and means for releasing said levers so as tocause en- 'gagement of the detent with said rack, said means extendingoutward through said casing.

3. In an automobile lock, the combination with a cylindrical casing, adiaphragm sei cured thereto, a toothed wheel engageable with saiddiaphragm, and a rack for actuating said toothed wheel, of a locksecured in said casing, lsaid lock having an extensible bolt, ahorizontal lever pivoted in said casing, a detent formed with the freeend of said lever engageable with the teeth of said rack, a pendantlever pivoted on the first named lever, said pendant lever having a partengageable by the bolt of said lock, a spring holding said detentnormally in engagement with the teeth of saidracl, and Y a plungeradapted to free said pendant lever from the first-named lever wherebythe detent is caused to engage with the teeth of the rack, when saidbolt is in an extended position. A In testimony whereof we have aixedour signatures.
